Cell sites’ energy costs cause a significant hit on overall network opex, and the hit promises to get even more painful as energy prices skyrocket worldwide. That’s why mobile operators have placed improving energy efficiency at the top of their task list.
Fortunately, operators have already discovered that one side benefit of their LTE upgrade efforts is the opportunity to make existing cell sites more green simply by adding newer and more compact base station equipment that consumes less power than older versions simply due to advances in technology. Further, the creation of heterogeneous networks via LTE Advanced specifications promise to allow operators to roll out more energy-efficient small cells in addition to, or sometimes even in lieu of, macrocells.
